Application July 13, 1946, Serial No. 683,538

2 Claims. (01. 155 152) This invention relates to collapsible or foldable chairs such as used on beaches and terraces in the summer-time.

It is an object of the present invention to provide in a foldable chair all of the features of a non-foldable chair of this type including arm rests, head rest, canopy and a rest for the foot or legs, and wherein all of these auxiliaries can be folded into main parts of the chair as it is folded up for transport.

It is another object of the invention to provide a novel means which is automatic for securing the head rest in its extended or raised position. According to the invention, the chair including the seat, back, front and rear legs are formed of U-shaped members having their free ends pivot-' ally connected at the point of their attachment to one of the other members whereby they may be folded into parallelism with one another when the chair is being folded. The seat, back and rear leg members are all connected to one an other at the same pivot. The forward leg member alone is pivotally connected to the forward portion of the seat member. The rear legs and the back members are retained when the chair is set up by back stops extending laterally from the ends of the seat member. The forward legs are retained against downward collapse by engagement with the under edge of the seat member. Pivoted to the lower end of the forward leg member is a foot rest to which in turn there is pivoted a sole support for the feet. A heel support can be dropped down from the sole support to support the heels. All of these foot rest parts are foldable into the front leg member at the time the chair is collapsed.

On the back member there is disposed a head rest which is slidable upwardly from the top of the back member to its adjusted position. This head rest has slots extending along its leg portions which receive the head rest stop secured to the top of the back member. These head rest stops have a guiding formation thereon by which latch elements on the head rest are guided during the upward movement of the head rest and cooperate with to retain the head rest in its raised position. The latch elements as soon as the head rest is raised are thrown across the slot and retained against vertical pivotal movement while bearing against the stop on the upper end of the back member by laterally projecting pins on the side of the slot opposite from the pivotal connection of the latch element with the head rest.

A canopy is adjustably connected to the top of the head rest.

Arm devices are foldable laterally inwardly from the point of connection of the bottoms of the vertical supports to the sides of the seat member. When in the raised position they are retained by latch members. The support within the seat and back is provided by the usual canvas web extending from the top of the back in concave fashion to the forward edge of the seat member.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawing forming a material part of this disclosure:

Fig. 1 is a perspective view of the chair unfolded and setup, except for the provision of the fabric seat therein, to receive a person.

Fig. 2 is a plan view of the chair when it has been collapsed or folded so that all of its parts lie substantially in one plane.

Fig. 3 is a front elevational view of the unfolded chair.

Fig. 4 is a side elevational view of the unfolded chair set up for use.

Fig. 5 is a cross sectional view, in elevation, of the chair set up for use as viewed along the line 5-5 of Fig. 3 looking in the direction of the arrows thereof.

Fig. 6 is a detail fragmentary view of the stops for supporting both the rear legs and the back in their extended positions.

Fig. '7 is a cross sectional view taken through the arm rest and showing the latch arrangement for connecting the same in its raised position to the seat member, taken along the line 7-1 of Fig. 5.

Fig. 8 is a view similar to Fig. '7, but with the arm rest folded down to its closed position.

Fig. 9 is an enlarged perspective view looking upon the bracket by means of which an upright member for the arm rest is pivotally connected to the seat member.

Fig. 10 is a fragmentary perspective view looking upon the top of the foot rest.

Fig. 11 is a similar view of Fig. 10 except that the heel rest has been raised to its out of use position and preparatory to the folding down of the foot rest into the chair.

Figs. 12 and 13 are top perspective views of a portion of the arm illustrating two types of holders, which can be folded under the arm rest, for supporting tumblers and plates respectively.

Fig. 14 is a folded perspective view of the top of the chair showing the head rest and canopy in their unextended positions.

Fig. 15 is an unfolded perspective view of the top of the chair showing the head rest and canopy in their extended positions.

Fig. 16 is an enlarged detail View of the stop for the head rest located on the back rest.

Referring now to the figures, the chair comprises generally a head rest l0, an adjustable back rest II, a seat l2, rear legs 13 and front legs 14, an adjustable foot rest l5, a support I6 for the sole of the foot and a support I! for the heel of the foot. All of these parts except the heel support, are of U-shape and are pivotally connected to one another, except for the head rest and rear legs, somewhat in chain fashion. The back rest, seat member and rear legs have their free leg ends interconnected to pivot about a common point. The angle of the back rest H is adjustable in relation to the chair by.- means of a spring bolt set within armrest 2.2; This bolt is so located as to adjustably align itself with corresponding holes in the back rest H1. The forward legs M are pivotally connected to the forward part of the. seat member and. the lower edge of the transverse section of the seat member serves as a stop to retain the legs 44 in their extended position. To fold the forward legs I4 into the chair as when the same is bein collapsed they are pivoted rearwardly whereas the rear legs l3 are pivoted forwardly. The foot rest 15 i pivoted by its free leg ends to the bottom of the forward legs and isretained in its extendedposition by the forward edge of the front leg transverse section.

The sole support i6 is similarly pivoted to the forward part of the foot rest and isretained in its raised-position by the upper-edgeof the transverse section of the foot rest 15. The heel support l-iis of flat stock and is-connected by hinges I8 to a transverse bar ill-extendingbetween the sides of the sole rest member I 6 (Figs; 10-and 11). A pivot latch 20 retains the heel support I1 in-its raised or folded up position. The heel support I1 is retained in its loweredposition by chains ZIat its opposite sides.

Referring nowparticularly'to- Figs; 1, '7; 8, 9, 12' and 13; 22- represents the armsof the chair to which there is rigidly connected to depend downwardly therefrom, arm supports 25, of which there are two for each arm. The lower ends of these arm supports 25 are pivotally connectedto brackets 26 secured to the inner faces of the leg portions of the seat member l2; Byt-his pivotal connection, the arms and'their supports canbe folded inwardly, as shown in Fig. 2, when the chair is being folded up for transport. The rearwardends of the arms are'cut out to'fit the side portions of the back I l as indicated at 2'? whereby to lock the back ll against forward displacement when these arms are intheir raised-position.

To look the arms in their raised position there is provided on the lower ends of the armsupports 25, pivoted arm latches 28 (Figs. '7 and 8) adapted to extend across the top edge of the leg portions ofthe seat member for engagement with the outerf-ace thereof, whereby to retain the arm supports vertically upright and the arms 22 locked with the back H. To fold up the chair thearm latch ZBis-raised upwardly and the arms and their supports are folded'into'the chair seat. In order to retain their latches when the arm supportsare being raised there is-provided on the arm supports arm latch stop pin 29,

The arms 22 may have on them and connected on their bottom faces to swing laterally outwardly therefrom, a glass or cup holder 23 or a foldable ruler like device 24 for retaining a sandwich plate or the like (Figs. 12 and 13) On the to of the head rest it), there is pivoted by its free ends U-shaped canopy member 30 (Figs 1, i, l4 and 15). In the forwardly extended position the canopy is supported by spring clips 3|. To fold the canopy into the chair it is pivoted rearwardly and dropped down onto the rear edge of the head rest. The canopy member can be covered in the usual manner with canvas.

On the sides of the back member ll there is secured laterally extending stops 32 adapted to extend through slots 33 in the sides of the head rest. Extensions of these stops 32 are winged to retain the head rest sides against lateral displacement and also to provide a stop surface on which a head rest lock element 3.1%. can: be. supported. to hold the head rest in the raised. position. When this look element 34?. is: turned forwardly it can ride downwardly or upwardly past the stop 32. In order forthis look element to function to retain the head. rest in the. raised position it is pivoted; rearwardly and; extended across. the slot space 33.: where it. is retainediat the opposite side of the slot and againstupward vertical displacement by a head: rest. stop pin 35. To release the head rest, the head rest israised and the lock element is swung. downwardly and to the side to clear thehead; rest.stop.3.2:. In. the release position the parts will. assume the. positions shown in Fig. 14.

In order that the back H; will be lockedgagainst rearward pivotal. movement and retained in. its proper upwardly extending position there is provided on the rearward endsof the seat. member legs, back stop portions 36 (Eig. 6). These portions 36 are in the form of platesextending laterally across the end and secured to inwardly bent ends or. flanges 310i theleg portionsof the seat member. The free ends ofthe rear leg member being. pivotedto the seat member on the same pivot pin as-the back rest-are disposed on the opposite sides of the seat legs and are retained against downward collapse when the-chair is set upby bearing directly against the lower edges of the inwardly extending flanges 31 The usual canvasfor-ming the seat in back'may be extended between the front edgeof theseat member 12 and the top of the backrest member ll-. As the chair is folded this canvas willbe foldedintoit. To first condition the-chair for folding, the arms are unlatched and swung inwardly- (Fig; 2) whereby the-back is released'and it can-be swung down, the-head rest having-been lowered thereon and the canopy swung to the rear. The heel support can be swung into the sole support and then the sole support folded down into the foot rest' member and'then these parts folded up into. the forward legs, Thereafter the forward legs and the parts canbe swung rearwardly. under the. seat and retained by the forwardswinging up of. therearwardleg portions whereby the. chair. is foldedand putin a collapsed condition to render it. suitable for transport. To unfold thechair. thereverse-sequence of operations is pursued;
